YouTube Analytics

YouTube Analytics Toolkit

Setup

Install dependencies:

cd scripts && npm install

Configure credentials by creating a .env file in the project root:

YOUTUBE_API_KEY=AIzaSy...your-api-key
YOUTUBE_DEFAULT_MAX_RESULTS=50

Prerequisites: A Google Cloud project with the YouTube Data API v3 enabled. Get your API key from the Google Cloud Console.

Quick Start

| User says | Function to call | |-----------|-----------------| | "Analyze this YouTube channel" | analyzeChannel(channelId) | | "Compare these two channels" | compareChannels([id1, id2]) | | "How is this video performing?" | analyzeVideo(videoId) | | "Search YouTube for [topic]" | searchAndAnalyze(query) | | "Get stats for this channel" | getChannelStats(channelId) | | "Get this video's view count" | getVideoStats(videoId) | | "Find channels about [topic]" | searchChannels(query) | | "Show recent uploads from this channel" | getChannelVideos(channelId) |

Execute functions by importing from scripts/src/index.ts:

import { analyzeChannel, searchAndAnalyze } from './scripts/src/index.js';
const analysis = await analyzeChannel('UCxxxxxxxx');

Or run directly with tsx:

npx tsx scripts/src/index.ts

Workflow Pattern

Every analysis follows three phases:

1. Analyze

2. Auto-Save

3. Summarize

High-Level Functions

| Function | Purpose | What it gathers | |----------|---------|----------------| | analyzeChannel(channelId) | Full channel analysis | Channel info, recent videos, avg views per video | | compareChannels(channelIds) | Compare multiple channels | Side-by-side subscribers, views, video counts | | analyzeVideo(videoId) | Video performance analysis | Views, likes, comments, like rate, comment rate | | searchAndAnalyze(query, maxResults?) | Search + stats | Search results with full video statistics |

Individual API Functions

For granular control, import specific functions from the API modules. See references/api-reference.md for the complete list of 13 API functions with parameters, types, and examples.

Channel Functions

| Function | Purpose | |----------|---------| | getChannel(channelId) | Get full channel details | | getChannelStats(channelId) | Get simplified stats (subscribers, views, videoCount) | | getMultipleChannels(channelIds) | Batch fetch multiple channels |

Video Functions

| Function | Purpose | |----------|---------| | getVideo(videoId) | Get full video details | | getVideoStats(videoId) | Get simplified stats (views, likes, comments) | | getMultipleVideos(videoIds) | Batch fetch multiple videos | | getChannelVideos(channelId) | Get recent uploads from a channel |

Search Functions

| Function | Purpose | |----------|---------| | searchVideos(query, options?) | Search for videos | | searchChannels(query, options?) | Search for channels |

Results Storage

Results auto-save to results/ with this structure:

results/
├── channels/       # Channel data and comparisons
├── videos/         # Video data and analyses
├── search/         # Search results
└── summaries/      # Human-readable markdown summaries

Managing Results

import { listResults, loadResult, getLatestResult } from './scripts/src/index.js';
// List recent results
const files = listResults('channels', 10);
// Load a specific result
const data = loadResult(files[0]);
// Get most recent result for an operation
const latest = getLatestResult('channels', 'channel_analysis');

Tips

1. Use channel IDs — Channel IDs start with UC (e.g., UCxxxxxxxx). You can find them in the channel URL or page source. 2. Request summaries — After pulling data, ask for a markdown summary with tables and insights. 3. Compare channels — Use compareChannels() to benchmark competitors side by side. 4. Batch requests — Use getMultipleChannels() or getMultipleVideos() for efficient batch lookups. 5. Search + analyze — searchAndAnalyze() combines search with full video stats in one call.
